Perhaps but he's been back in AAA for over a month(32 games to be precise). That's a fairly lengthy time to rehab if they felt he was ready for the majors. La Stella for example after returning to AA after re-injury spent 20 days in AA/AAA for 19 games(8/2 thru 8/22).
Baez wasnt called up because once he went through his bereavement, played, got hurt, and got back again. .
There was no where to play him everyday. ..
Even after they benched Castro, Maddon stayed with Cogs who was swinging a solid bat from left side and was key to their hot streak..
So, you can analyze it to death but bottom line is , he remained in Iowa because they weren't going to bump anyone who was already playing. . Plus who knows, maybe a whole season down in Iowa may end up being benificial for him as a player in the long run..
Now on how many AB he ends up with in September..
That going to depend on how he plays..
I think with Soler out and Castro most likely not in their future plans for 2016 now, baez will get the nod at 2B come Tuesday with Cogs in RF and will continue to get the nod as long as he plays well. mainly because, although he might be their 2Bmen in 2016, their still in a playoff race and need to keep winning.
